Question

If temperature of an object is $140 \,{}^\circ F$ , then its temperature in centigrade is

• A. $105^\circ C$
• B. $32^\circ C$
• C. $140^\circ C$
• D. $60^\circ C$

Answer 1

Answer: (D)

Relation between $^\circ C$ and $^\circ F$ ,
$\frac{C}{5}=\frac{F - 32}{9}$
$\Rightarrow \, \frac{C}{5}=\frac{140 - 32}{9}$
$\Rightarrow C=60^\circ C$
